Beginning on or about Saturday, July 6, at 5 a.m. through Sunday, July 7, at 6 p.m., Dulles Corridor Metrorail Project (DCMP) crews will be performing civil work, requiring the full closure of a portion of the westbound Dulles International Airport Access Highway (DIAAH). At mile marker 9.1, traffic will be redirected to the left lane of the westbound Dulles Toll Road (DTR) from the Dulles International Airport Access Highway (DIAAH). There will be a second left DTR lane closed as a buffer. At mile marker 1.7, near the Route 28 toll plaza, traffic will be able to re-enter the DIAAH towards the airport. The ramp to the westbound DIAAH at mile marker 9.0 and 3.3 will be closed to traffic.

All work is weather dependent and subject to change. Drivers are asked to use caution and pay attention to all signage and barricades. Large, slow-moving vehicles may be exiting and entering the highway at various times.
